ATTACHMENT FOR WAGONS FOR LOADING OR UNLOADING STONE.

SPECIFICATION forming part of Letters Patent No. 623,676, dated April25, 1899.

Application filed April 4,1898. Serial No. 676,371. (No model.)

To (LZZ whom, it may concern:

Be it known that I, JULIUS IV. KNOPP,of Toledo, county of Lucas, andState of Ohio, have invented certain new and useful 1m provements inPortable Attachments for Wagons for Loading orUnloading Stone; and I dohereby declare that the following is a full, clear, and exactdescription of theinvention, which will enable others skilled in the artto which it appertains to make and use the same, reference being had tothe accompanying drawings, and to the figures of reference markedthereon, which form part of this specification.

My invention relates to a portable attachment to wagons for loading andunloading stone, and has for its object to provide a mechanismtransportable with the wagon, whereby when either at the source ofsupply or delivery the mechanism may be erected and operated to eitherload upon the wagon or deliver the load from the wagon to the desiredplace of deposit.

Figure l is a side elevation showing the truss-winch and tackle. Fig. 2is a top plan view. Fig. 3 is a rear end elevation. Fig. 41: is a detailView showing the carrier-beam and traveler. Fig. 5 is a view in sideelevation of a section of carrier-beam with the traveler thereon. andlink which supports the traveler-beam.

I have constructed a wagon'with my improved attachment in which thedivergent sills are of I-beam iron, and suspend the sills by stirrups 2,although I may employ the ordinary wagon constructed for transportingstone, and upon the bed of the wagon I erect a truss 3, preferably ofT-beam iron, the side rail of the truss converging to a center, as at 4,and at this point I journal a sheave 5, preferably of three sections,and intermediate the length of one of the divergent sections of truss,as at 6, I journal a winch 7, over which is reeved a rope or cable 8,and mount upon the shaft of the winch a drum 9, having perforations toreceive the end of a bar 11, by which to revolve the winch. The rope orcable 8 is also reeved over the sheave 5, and one or more strands arereeved over a pulley 12 of a block 13, having a link 14, in which restsone end of a traveler-beam 15, by which means when the drum 9 isrevolved the traveler-beam is either raised or lowered,

Fig. 6 is a detail View of the block' as desired. The traveler-beam 15is supported at the opposite end upon a standard 16, the base of whichmay rest upon the curbing 17, and is formed with notches or rests 18,into which a link 19, secured to the travelerbeam, may rest.

I mount upon the traveler-beam 15 a block 20, having a roller 21, whichrests upon the beam, and in the frame 22 of the block there is passed arope or cable 23, which acts as a sling to embrace the load 24 of stoneeither by being secured to metal hooks 25 or otherwise.

It will be evident that I may strengthen the framework by truss-irons,as shown at 26 in Fig. 3, or in any preferred manner.

In the employment of the skeleton metal bed of I-beams l I may providefor a resilient movement to compensate for unevenness of the road byinterposing a spring 27 upon the front axle 2S, and to lend rigidity Imay secure a brace-iron 29 upon the truss and allow the opposite end 30to embrace the standard 31, upon which the spring 27 is coiled.

, In operation the wagon is driven to the source of supply of the stone,the standard 16 is erected, and the link 19 adjusted in one of thenotches 18 to incline the beam 15 toward the wagon, the pulley 12 beingalso lowered by manipulating the winch. The sling is now secured aroundthe stone and the beam 15 slightly raised by elevating the pulley 12complish the work hitherto requiring three or four.

I prefer to drill holes along the top portion of the beam 15, into whichmay be inserted stop-pins 32 to limit the movement of the sling andload. 7

It will be understood that the drum 9 and shaft are controlled by theusual ratchet and pawl to control the winding up of the load and with afriction-brake to allow a controlat one end, the other end beingadjustably supported by a standard having a serrated edge, and atraveler upon the beam adapted to travel in the direction ofinclination'of the beam.

In testimony that I claim the foregoing as my own I hereby aifix mysignature in presence of two Witnesses.

JULIUS V. KNOPP.
